HELP! fitness first mt gravatt SPIN CLASS?

[holly]

i have recently joined fitness first @ Mt Gravatt, Brisbane. Im wanting to do a spin class. i am just wondering do you just rock up outside to class at the allocated time eg. 5.45pm outside to door. OR do you put your name down? on a list? i believe it is always quiet popular..im fat spinning will burn. i will then become more confident!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
